Specification of Letters Patent.

Application filed March 12, 1912.

Patented Jan. 7, 1913.

Serial No. 683,269.

To all whom it may concern:

Be it known that I, JULIUs Hess, a subject of the Emperor of Germany,residing at Strassburg-Neudorf, in Alsace-Lorraine, Germany, haveinvented new and useful Improvements in Machines for Cutting the Hair orFur of Skins, of which the following is a specification.

This invention relates to an improvement in cutting fur or hair fromskins.

The fur or hair of skins, especially of rabbit skins required for themanufacture of hats and other felted goods, must not be pulled apart .incutting or shearing, but must remain together after being cut off in thesame relative position as it occupied when on the skin. WVith thisobject in view, the hair of such skins has mostly been cut off by theaid of very quickly revolving disk knives but this tended to cause(through the air current produced by the rotation of the knife) a largequantity of waste. It is moreover known to cut the hair from such skinsby means of a knife moving up and down, but the necessary speed cannotbe attained with such a device.

In the present invention the cutting knife is moved in the mannerhereinafter set forth by means of two eccentrics which give it a to andfro mot-ion. By this meansthere is obtained a great rapidity of motionfor the knife and at each motion to and fro of the knife a cuttingaction takes place and finally by reason of the sloping thrusting cutsmooth removal of the hair is attained. The skin with the hair sidedown- Ward is drawn forward by the delivery rollers against the cuttingmechanism. The rollers are only move-d from time to time and this alwaysafter the conclusion of a cutting stroke whereas they are static-naryduring the cut. According to the kind of skins operated upon, therollers are brought nearer to the cutting mechanism or farther removedfrom it.

The invention is illustrated in the drawing as follows:

Figure 1 shows a front elevation. Fig. 2 a plan view and Fig. 3 asectional view.

The points of the hair are held back on the advance of the skin throughthe rollers a, Z), so that the part of the skin which lies between thecutter and its opposite blade is cut off and the hair itself becomesfree while the fragments of skin fall down in thin strips together withthe roots of the hair. The hair which holds together in the naturalposition and is separated from the hair roots, slips down over a guide 0and is received upon tables in the well known manner or is carriedfarther by mechanically operated bands. The cutting off of the particlesof skin is effected as stated, by aid of the cutter s, which is securedupon a bar held by the eccentric rings 6. The eccentrics u move indirections opposed one to the other. The actuation of the eccentricshaft r is effected by the aid of a belt 1) and pulley 72. The eccentricshaft 3/ is driven from the eccentric shaft 1" by a twisted belt 2.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed I declare thatwhat I claim is:

1. A fur or hair cutting machine comprising in combination, means foradvancing the skin, a relatively fixed knife, a coacting knife, androtating devices imparting a longitudinal shearing and a to and fromovement to said coacting knife, substantially as described.

2. A fur or hair cutting machine comprising in combination, a relativelyfixed knife, means for advancing the skin thereto, a coacting knifeblade and an eccentric device at each end of said coacting blade forimparting a shearing and a to and fro movement thereto, substantially asdescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JULIUS HESS.
